To all whom t may concern.

Be it known that JOHN F. MCCOY, now deceased, of whom the undersigned,MARY MCCOY, who resides in the city of New York, borough of Brooklyn, inthe county of Kings and State of New York, is the duly appointedadministratriX, has invented a certain new and useful Improvement inTrain-Stopping Trips or Obstacles, of which the following is a full,clear, and exact description.

Thisapplication is a division of an application for United StatesLetters Patent filed by the said John F. McCoy, Number 864,403, @ctober1, 1914.

This invention relates to train stopping trips or obstacles adapted tobe set up in the track by a trainman of a train that has been stopped,so as to protect such stopped train from accident by a succeeding traincollidingwith it.

The invention has for its general objects to improve the construction ofdevices of this character so as to be reliable and elflcient in use,comparatively simple and inexpensive to manufacture, and so designedthat when it has performed its function it automatically moves toinoperative position so that the track will be clear for traffic.

A more specific object of the invention is the provision of a staff-liketrip having hingedly connected sections pivoted on different centers insuch a manner that these sections can be held together in uprightposition by means which can be destroyed by the burning of a time fuseor by the blow of a train-carried element, whereupon the sectionsautomatically swing downwardly to an inoperative position.

Another object of the invention is the provision of'a combined `trip andsignal having the characteristics above referred to in combination with'means whereby the combined trip and signal can be positioned in only oneway in the track. y

Another object is to provide a train-carried stopping device so designedas to operate to destroy an element which holds the two sections of thestaff in upright position. With such objects in view, and others whichwill appear as the description proceeds, the invention comprises variousnovel features of construction and arran ement of parts which will beset forth wit par-i ticularity in the following description and claimsappended hereto.

In the accompanying drawings, which illustrate one embodiment of theinvention and wherein similar characters of reference indicatecorresponding partsV in all the views,

Fig. 10 is a detail side view of a portion of the trip; and

Fig. 11 is a vertical section o-f the signal fuse.

Referring to the drawing, A designates portion of the a trip-operatedtrain stopping device whichv includes a valve or equivalent device 1suitably carried by the train or car, whereby the propelling power canbe cut of or the brakes set, or both, the device 1 being'actuated by arock shaft 2 carried by a suitable part 3 of the locomotive or car, andon this rock shaft are oppositely extending arms 4 and 5 that areconnected by links 6 and 7 with a pivoted trip-engaging element 8. Thiselement is a frame of shallow V-shaped form in side view and comprises apair of forward bifurcations 9 and a pair of rearward bifurcations 10,there. being inclined surfaces 11 at the center of the device 8 andbetween the bifurcations, each inclined surA face serving to have awiping action on the trip, whereby the element 8 will be swung from itsYnormal position so as to operate through the links 6 and 7 to actuatethe device 1. The device 8 is pivoted on a bracket or hanger 12 to swingon a center 13, and the links 6 and 7 are connected at 14 and 15 withthe element 8 at opposite sides of the center 13.k The opposed faces 16of the bi-v The trip device Bis in the form of a staff r which has anon-circular lower end-18 to tit in a correspondingly shaped socket 19of a socket plate 20. The socket plates 20 are permanently positioned inthe track at suitably spaced intervals, and preferably each socket.plate rests on a tie 21 and is fastened thereto f in any suitablemanner, as, for instance, by

spikes 22, Fig. 7, and by bolts 23 which pass through eyes 24 at one endof the socket plate and through a track rail 25.

The upper part of the staff-like tripA B is composed of two sections ormembers 26 and 27 which are connected by pivotsV 26a` and 27L with thebase 28 of the staif. The pivotal centers 26a and 27a are arranged atdifferent l y levelsso that ,the two sections 26 and 27 cannot Swinginparallelism, and consequently, if the two sections are held togetherthey will remain in a vertical position against the action of theirrespective springs 29 and 30.

These springs are mounted on the base 28 and bent to throw the sections26 laterally from a vertical position, or to the left in Fig. 8. Thesections 26 and 27 are held together by a mutilatable and fusible ring31 )applied to the upper end of the trip, and

when this ring is destroyed the members 26 and27 will move from avertical operative position to a lateral inoperative position To assistin the proper mating of the mem- `"bers 26 and 27 one is provided with alongitudinal rib 32 and the other with a longitudinal groove 33 into.which the rib tits, as

shownin Fig 9. The ring 31 is adapted to be struck by they serratedsurfaces 17 of the v train-carried stop element 8, and the serrationsdestroy the rings so that the trip will move to inoperative position,but before the members' 2,6 and 27 of the trip can move toinoperativeposition they engage the inclined surface; 11, whereby thestoppingy device is operated, and afterx the element passes.y the tripthe members 26 and 27 swingl in a directiontra-nsverse to the trackontheir pivots .26? and 27a, and assume an inoperative posi- Y tion` .Ifa.visual'signalisdesired for day use, a flag-234 asindicated by dottedlines, Fig; 8, canbe held in a socket 35 on one of the mem'-- bers ofthetrip. For signaling by night a` .fcolonedf light fuse Cl may beapplied'to the tri-p, such fuse having. itslower endl 36 con"- structedto enter a socket 37 formed by makingrecessesv in. the members 26 andi27 of the trip, the ring 31 having a mouth 3S for facilitating theentrance of the signal device C into the trip. The device C comprises arod of suitable inflammable material 39 having a protective casing 40and a protective cap 41'. On the bottom of the fuse C is a conical hood4:2 which is disposed over the fusible ring 31, so that the latter ywillnot be melted" by the hot residue of the burning fuse until the fuse isalmost entirely burned up, when the ring 31 will be permitted to meltand allow the trip to move to inoperative position. It is to beunderstood that the fuse C will burn a predetermined length of time toenable a train to proceed far enough to be out of the danger zone of asucceeding train, andthe fuse finally performs the function of renderingthe trip inoperative, but if a-succeeding train should proceed withoutheeding the fuse, the trip device will be operative to stop such train.The bottom of the fuse is so constructed that it will havedirect Contactwith the ring 31, so that the inflammable material of the fuse willfinally ignite for the purpose just mentioned.

From the foregoing description taken in connection with the accompanyingdrawing, the advantages of the construction and method of operation willbe readily understood by those skilled in the art to which the inventionappertains, and while l have described the principle of operation,together with the device which I now consider to be the best embodimentthereof, I desire to have it understood that the device shown i ismerely illustrative and that such changes may be made when desired asfall within the scope of the appended claims.

Having thus described the invention, I
